Without the air, cooling is only through radiated heat (and evaporation in things that are not packed airtight, freezer burn much?) which is a lot less effecting.
This means that it's useless for cooling things down fast enough to keep bacteria from growing like crazy.

well what about just a deep freeze? like i mentioned in the post right before yours. could you get food and pre freeze them to w/e temperature required(for best results) then place them in the deepdreeze, maybe on a block of ice(idk).
then suck the air out....
would the "product" retain its frozen state for longer?
and if it would then you would be able to put regular items in there as well, like apples you want too keep fresh for a long period of time?
like...with the apples you would put them in the fridge and let them get the temp they usually get...then put them in the deep freeze. you wouldnt even need a divider. bc the vacuumed space would be sufficient enough?
most of what i typed were secretly questions.
yeah...
